Database administrators can shift workloads between platforms as needed. For example, they can run development and testing in the cloud and shift applications back to local infrastructure for processing. Or they can replicate workloads to one or more cloud regions for backup and recovery purposes.
The hybrid model “lets you keep hard copies of your data while still allowing remote access to employees,” said Chris Riley, CEO of USA Rx, a digital health marketplace.
“This is extremely useful now that much of the workforce has transitioned to working from home.”
What About Implementing?
But migrating to and managing a hybrid environment is challenging. Data integrity must be maintained. Copies of production data can’t be allowed to proliferate and create confusion or errors. Security is a concern when data traverses public networks and management complexity grows with the number of database platforms involved.
“Hybrid cloud databases are hard to implement,” said Caroline Lee, co-founder of CocoSign, a developer of digital signature software.
“They need to comply with legacy systems the company is using, the service provider must be flexible, a new administrative team may need to be hired and there are governance challenges.”
Nevertheless, the cost savings, reliability and flexibility payoffs are often worth the extra effort, she noted.
Applications that use data must also be aware of where it’s located.
“There’s a whole re-architecting required to take advantage of the public cloud environment,” said Chris Paap, senior solutions marketing manager at Nutanix
“It’s not just moving a database; it’s also all the applications and reporting. You need to [operate in the] public cloud but manage like the environment is on-premises.”
Those data integrity measures are one application of hybrid cloud databases that Nutanix is targeting with Nutanix Era, a database as a service (DBaaS) custom made for the Nutanix platform for running databases that automate and simplifies database administration on-premises and in the cloud.
Paap said the software provides one-click simplicity and invisible operations to database provisioning and life cycle management (LCM) such as cloning, patching, and backing up databases, manage consistency across multiple platforms. Equally important is that Nutanix Era simplifies the hybrid cloud database environment by abstracting away much of the complexity of managing multiple discrete systems.
“For example, if you’re going to run on AWS you have to become an expert in RDS,” which is the cloud giant’s distributed relational database service, Paap said.
“Your company policies and practices have to shift and it’s a learning process.”
